(CNN) โ€” North Korea's sixth nuclear test was so powerful that it's still triggering earthquakes more than a year later.

South Korea's Meteorological Administration (KMA) said a small quake that hit in North Korea's North Hamgyong province Wednesday was induced by the September 2017 underground detonation of a nuclear device.

That nuclear test was North Korea's most powerful to date, with an estimated explosive yield of 160 kilotons, according to Japan's Defense Ministry. The blast created an initial 6.3-magnitude tremor, caused a series of aftershocks and reportedly an on-site collapse.
